Rafe understood Avilina's message and he also knew that what she just said was the promise he made as a member of the guild.
Twenty years ago, he was among the very few people who managed to escape the execution. His father was the General of the Varian Army and he was among the ones who were executed with General Lanardo Varian and his wife. He was only 4 back then.
It was his mother who ran away with him as per his father's wish but the wound in their hearts was never healed. It was why when Avilina worked on gathering the remnants of the traumatic incident, his mother didn't hesitate to join them.
It was not like they had a better choice as they had to live in constant fear of exposure wherever they went.
Growing up, he became one of the people who closely assisted Avilina because he was the son of Commander Lanardo's trusted General. Not to mention that he had long vowed to help Avilina and do anything possible to realize their goals.
